https://bugzilla.novell.com/show_bug.cgi?id=871817 https://bugzilla.novell.com/show_bug.cgi?id=871817#c2 --- Comment #2 from Robert Milasan 2014-04-03 11:46:25 UTC --- No, there seems to have no change, but on the other hand I have firefox, chrome and other apps running which use CPU and I/O, but still ls or lsusb or uname are slow in the terminal. I'll try in the console to see if there is any difference. BTW: if this helps, this is the output of cmdline: robert@viper:~> cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-3.14.0-2.gfa168d7-desktop root=/dev/sda5 selinux=0 apparmor=0 resume=/dev/disk/by-uuid/987ef39a-a7eb-4c0c-a951-1a19f63e8293 splash=silent quiet rootfstype=ext4 libahci.ignore_sss=1 raid=noautodetect plymouth.enable=0 intel_idle.max_cstate=0 processor.max_cstate=0 idle=mwait nmi_watchdog=0 audit=0 net.ifnames=0 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This happens already on 2 machines, initially was thinking is Firefox, but Firefox wasn't updated at all nor glibc or something related to Firefox. On the second machine (a Dell laptop), the commands don't seem to have the same issue as I initially reported, but I have the Firefox issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The command line, yes, it's slow at least the first time. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It's a small server, but haven't see any symptoms on that machine. On my other machine, the symptoms are not the same, the command line doesn't seem to be that affect, but still it's somewhat sluggish and Firefox hangs (haven't seen Firefox hang with kernel 3.14.1, but still there is time). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Is it possible some configuration issues? Something is enabled in the kernel which causes this? robert@viper:~> uname -a Linux viper.suse.cz 3.14.1-1.geafcebd-vanilla #1 SMP Mon Apr 14 20:10:59 UTC 2014 (eafcebd) x86_64 x86_64 x86_64 GNU/Linux One thing I've noticed is that now the slowness is at the end, meaning exiting the program or command. So when running 'time lsusb' for example, all is good, I'm getting real/user/sys info and looks good, but after 'sys' info is displayed by time command, it takes a while to actual finish (a couple of miliseconds to a second or two). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've tested kernel-vanilla and kernel-desktop, both work as expected (meaning no delays or sluggishness). At the moment I'm not sure which option 'intel_idle.max_cstate=0' or 'processor.max_cstate=0' is to blame. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
